WebTrader Hosted Solution (WTHS)

The FDA ESG offers WebTrader users an additional capability: the WebTrader Hosted Solution (WTHS).


What is WTHS?

WTHS is a web-based solution that will eliminate the need for installing JRE (Java Runtime Environment) on the user’s machine. The benefits of WTHS are:

  • WTHS eliminates the need for JRE installation and maintenance for WebTrader users’ computers
  • WebTrader users can make submissions from both Windows and Mac operating systems
  • Users may make submissions from almost any Web Browser


For more information on WTHS, please read below and visit WTHS FAQs


Is WTHS replacing WebTrader?

No, WTHS is an alternative to utilizing the computer-based application from a specific computer for making submissions to FDA. WTHS is an additional FDA service capability that can eliminate the need for the user computer JRE-based method for submitting to the WebTrader. It also provides submission process redundancy in case of a user not being able to access the JRE computer.

Users opting for WTHS will have an additional login (in addition to WebTrader login).

The WTHS Tutorial outlines how the WTHS and WebTrader account login and submission process works.


Are there any requirements to utilize WTHS?

The following rules apply for utilizing WTHS

  • WTHS login session will have a limit of 60 minutes per login
  • WTHS option is recommended for submissions smaller than 250MB
  • Only one login session is allowed per user
  • Only one WTHS account is allowed per individual users. Users that have multiple WebTrader accounts will only be issued one WTHS account
